The restrictions, which are part of B.C.’s oil spill response plan, could heavily impact Kinder Morgan’s Trans Mountain pipeline expansion.

The proposal would look at increasing restrictions on diluted bitumen transportation by pipeline or rail until the “behaviour” of spilled bitumen can be better understood and a response plan can be made.

Notley has accused Horgan’s government of making a “provocative and unconstitutional” threat.

“Under the Canadian constitution, B.C. has no authority to impose such a regulation,” she said.

“It’s unconstitutional and it is an attack on Alberta’s primary industry and the hundreds of thousands of jobs across the country that go with it.”

Notley declined to provide further details on her government’s next steps.

“We don’t want to do anything that causes more harm to the Alberta economy than it does to the B.C. economy.”

“For the time being, we’re prepared to give them a little bit of time to talk. We’re talking days, not much more than that,” said Notley.

“The federal government gets the ridiculousness of [B.C.’s proposal] as much as we do but sitting back and letting B.C. threaten [the expansion] and not doing anything to tell them to pull back the threat… they’ve got to stop talking about their ability to do something illegal.”

Notley said that her government will launch a series of “online tools” Tuesday that will allow Albertans and Canadians across the country voice their displeasure with B.C.’s actions.
